Replacing the valve cover gaskets on my 2004 Jeep Grand Cherokee 4.7HO with 151k miles. Bought it in 2010 with 90,000 miles, do not know previous oil change history, but i have changed the oil every 5-6000 miles with Pennzoil platinum or ultra 10w-30 since I purchased it. I love this jeep, It will take me anywhere and has never let me down. Enjoy the pictures.
